This is what I meant, yes. AFAIK auto and allow-hotplug are mutually
exclusive, but interfaces(5) is a bit unclear in that point.

There are at least two use cases:
- A network device might not always be present (such as a USB WLAN
adapter), and you want to bring up the interface automatically
whenever you plug in the device.
- You use DHCP to get an IP. IIRC, dhclient will run in the foreground
and thus slow down the boot process if the interface is "auto"; but it
nicely runs in the background if the interface is "allow-hotplug".
Since Foss User has a static IP and probably not a removable network
card, neither of these reasons apply.
